The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [2]
The carrier aircraft first flew in April 2019, at the Mojave Air and Space Port, reaching 15,000 ft (4,600 m) and 190 mph (305 km/h) during a 2 hour 29 minute flight. [ 8 ] [ 9 ] Stratolaunch underwent a change of ownership and direction when Jean Floyd took over as CEO in 2019, reacquiring staff and growing to 87 employees by the beginning of ...
The DF-ZF is thought to reach speeds between Mach 5 (3,836 mph (6,173 km/h; 1,715 m/s)) and Mach 10 (7,680 mph (12,360 km/h; 3,430 m/s)). [5] The glider could be used for nuclear weapons delivery but could also be used to perform precision-strike conventional missions (for example, next-generation anti-ship ballistic missiles), which could penetrate "the layered air defenses of a U.S. carrier ...
Stratolaunch was then reported to be aiming for a first flight within a few weeks and a first launch from the carrier in 2020. [24] The aircraft first flew on April 13, 2019, at the Mojave Air and Space Port, reaching 17,000 feet (5,200 m) and speed of 165 knots (306 km/h) in a 2 hours 29 minutes flight. [25]
In December 2014, NASA awarded Lockheed Martin a contract to study the feasibility of building the SR-72's propulsion system using existing turbine engine technologies, The $892,292 (~$1.13 million in 2023) contract funded a design study to determine the viability of a TBCC propulsion system by combining one of several current turbine engines, with a very low Mach ignition Dual Mode Ramjet (DMRJ).
The HSTDV is an unmanned scramjet demonstration aircraft for hypersonic flight.It is being developed as a carrier vehicle for hypersonic and long-range cruise missiles, and will have multiple civilian applications including the launching of small satellites at low cost.
Hypersonic cruise missiles and hypersonic glide vehicles have the ability to maneuver — to evade air defenses, for example — at speeds in excess of Mach 5, something the Kinzhal cannot do.
The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1. The critical Mach number (Mcrit) is lowest free stream Mach number at which airflow over any part of the aircraft first reaches Mach 1. So the subsonic speed range includes all speeds that are less than Mcrit.
